remote power switch

I have an old computer without a chassis which I want to do some testing on. The problem is that the ATX power supply I'm using doesn't have an on/off switch so I have no way of turning it on. My question is: Will it help to short the remote power switch connector on the motherboard with a jumper, or is that a bad idea?

Yes, that's what I was thinking too. The main point of my question was to hear if it might harm the motherboard if I did it. I don't know much about electronics, so I don't really know what could happen.

Well, now I've tried it, and it didn't work. Nothing happened when I plugged in the power cord. Any further help on how to be able to turn on this computer is appreciated. The relevant pin assignments can be seen here: http://www.idi.ntnu.no/~runeberg/pins.jpg

Poor audio quality is one of the top reasons people don’t use video conferencing. Get the crispest, clearest audio powered by Dolby Voice in every meeting. Highfive and Dolby Voice deliver the best video conferencing and audio experience for every meeting and every room.

unplug the PS. Look for a green and a black wire in the MB connector and jump them with a wire or paper clip. Plug in the power supply and see if it runs. You have to have it connected to at least one drive.

I do this all the time. I short the jumper where the remote power switch plugs into the board, with a screwdriver. It never harms the board. UNLESS you are shorting the wronnnnnnnnngggg ones. So be careful. Refer to the manual for the correct jumpers. And as far as I can tell, you do not need a Drive plugged in. I have never had to, unless it is a special power supply.

You should not get a shock through the screwdriver to motherboard...
you are just shorting a jumper...closing a circuit....I do not know what kind of voltage is passing thru. I just know i have been doing this to test moboards w/out having to plug in all the crap. As well as test power supplies...worked fine for me for years now...
